µTasker general / Tasks in polling mode.

« on: March 18, 2008, 09:31:10 PM »

Hi Mark,

I've made some tests with tasks in polling mode to measure how fast they can run using an oscilloscope (toggling a pin).

When I run my toggle task with all the other default tasks, the periodicity was about 14us.
Running just my task, the periodicity was about 5us.

Are these delays typical? I thought a little slow to a 60MHz processor.

Thanks again.

Hi Mark,

A debounce timer after the event seems to be the best solution.

Thanks again for all your support.

Hi Mark,

I'm using the serial port to create a RS485 Bus, however in half mode.
In this case, I need to guarantee that all output buffer was sent and then change the 485 driver from transmit to receive mode, in other words I have to wait something like UART_TEMP = 1 (Transmit Buffer Empty), so my question is: Can uTasker generate any unsoliceted event to show me that the transmit buffer was really sent?
If no, which would be the most suitable way to do this?

Thanks

Fausto
